|

|

|
|
This class is derived from \helpref{wxHtmlParser}{wxhtmlparser} and
|
||
|
|
its mail goal is to parse HTML input so that it can be displayed in
|
||
|
|
\helpref{wxHtmlWindow}{wxhtmlwindow}. It uses special
|
||
|
|
\helpref{wxHtmlWinTagHandler}{wxhtmlwintaghandler}.

\begin{enumerate}
|
||
|
|
\item Product of parsing is wxHtmlCell (resp. wxHtmlContainer) object.
|
||
|
|
\item This parser produces temporary data! You should call
|
||
|
|
\helpref{delete GetTempData()}{wxhtmlparsergettempdata}!

|
|
\func{}{wxHtmlWinParser}{\param{wxWindow }{*wnd}}
|
||
|
|
|
||
|
|
Constructor. Don't use the default one, use constructor with
|
||
|
|
{\it wnd} paremeter ({\it wnd} is pointer to associated \helpref{wxHtmlWindow}{wxhtmlwindow})
|
||
|

\membersection{wxHtmlWinParser::SetDC}\label{wxhtmlwinparsersetdc}

||
|
|
|
||
|
|
\func{virtual void}{SetDC}{\param{wxDC }{*dc}}
|
||
|
|
|
||
|
|
Sets the DC. This must be called before \helpref{Parse}{wxhtmlparserparse}!
|
||
|
|
|
||
|
|
\membersection{wxHtmlWinParser::GetDC}\label{wxhtmlwinparsergetdc}
|
||
|
|
|
||
|
|
\func{wxDC*}{GetDC}{\void}
|
||
|
|
|
||
|
|
Returns pointer to the DC used during parsing.
|

|
|
|
||
|
|
\membersection{wxHtmlWinParser::GetCharHeight}\label{wxhtmlwinparsergetcharheight}
|
||
|
|
|
||
|
|
\constfunc{int}{GetCharHeight}{\void}
|
||
|
|
|
||
|
|
Returns (average) char height in standard font. It's used as DC-independent metrics.
|
||
|
|
|
||
|
|
{\bf Note:} This function doesn't return {\it actual} height. If you wanna
|
||
|
|
know height of current font, call {\tt GetDC -> GetCharHeight()}
|
||
|
|
|
||
|
|
\membersection{wxHtmlWinParser::GetCharWidth}\label{wxhtmlwinparsergetcharwidth}
|
||
|
|
|
||
|
|
\constfunc{int}{GetCharWidth}{\void}
|
||
|
|
|
||
|
|
Returns average char width in standard font. It's used as DC-independent metrics.
|
||
|
|
|
||
|
|
{\bf Note:} This function doesn't return {\it actual} width. If you wanna
|
||
|
|
know height of current font, call {\tt GetDC -> GetCharWidth()}
|

|
|
|
||
|
|
\membersection{wxHtmlWinParser::GetWindow}\label{wxhtmlwinparsergetwindow}
|

|
|
|
||
|
|
\func{wxWindow*}{GetWindow}{\void}
|
||
|
|
|
||
|
|
Returns associated window (wxHtmlWindow). This may be NULL! (You should always
|
||
|
|
test if it is non-NULL. For example {\tt TITLE} handler sets window
|
||
|
|
title only if some window is associated, otherwise it does nothing)
|
||
|
|
|
||
|
|
|
||
|
|

(If the font was already created only a pointer is returned.)

|
You must call \helpref{delete myparser->GetTempData();}{wxhtmlparsergettempdata}

|
|
to free the memory!
